It is often argued that a mandatory minimum wage is binding only if the wage density displays a spike at it. In this Paper we analyse a model with search frictions and heterogeneous production technologies, in which imposition of a minimum wage affects wages even though, after imposition, the...

This Paper presents strong evidence for the concavity of wages in job and worker characteristics by adding second order terms to a Mincerian earnings function for six OECD countries. Under a standard normality assumption, this concavity cannot be attributed to unobserved components in those...

In 1990 Colombia replaced its traditional system of severance payments with a new system of severance payments savings accounts (SPSAs). Although severance payments often are justified on the grounds that they provide insurance against earnings loss, they also increase costs for employers and...

Firms are the field of several strategic interactions that standard neo-classical analysis often ignores. Such strategic considerations concern relations between capital owner and labour, relations between marginal employees and incumbents and more generally all relations between different...

This paper examines competitive search equilibrium when workers' effort choice and 'type' are private information. We derive a modified Hosios Rule determining the allocation of resources, and analyze how private information influences the responsiveness of the unemployment rate to changes in...

In this paper we study the relationship between labour market institutions and monetary policy. We use a simple macroeconomic framework to show how optimal monetary policy rules depend on labour institutions (labour adjustment costs, and nominal and real wage rigidity) and social preferences...

This paper studies the joint distribution of wages and employment levels in simple matching models of job creation and destruction with costly search and firm-specific labour demand shocks. Existing evidence on the relationship between employer size, the mean and variance of employees' wages,...

Unemployment insurance systems include monitoring of unemployed workers and punitive sanctions if job search requirements are violated. We analyze the effect of sanctions on the ensuing job quality, notably on wage rates and hours worked, and we examine how often a sanction leads to a lower...

The proposition that labour market adjustments to intra-industry trade are less costly than adjustments to inter-industry trade is a widely-held belief amongst trade economists. If it is the case that there are significant sector-specific skills, then this ‘smooth adjustment hypothesis’...
